Astrium-Allsat JV Launches GNSS Reference Network Services across Europe


Astrium Services and Allsat GmbH network+services have created a joint venture, AXIO-NET GmbH, to offer precise navigation and positioning services across Europe.

The companies, which formed a JV in September 2007 to operate the German ascos service, have created a trans-European brand — AXIO-NET  — to extend the service, based on a network of reference stations that generate high-accuracy differential corrections of GPS and GLONASS satellite signals.

China's Compass/Beidou: Back-Track or Dual Track?

China’s Compass/Beidou: Back-Track or Dual Track?

A recent presentation on Compass/Beidou that appeared to reflect a step back from China’s GNSS program more likely represented a step sideways — and an implicit acknowledgment of the complex political and technical elements involved in such an enterprise.

In February 20 remarks at the Munich Satellite Navigation Summit in Germany, Jing Guifei, a project manager at the National Remote Sensing Center of China (NRSCC), seemed to play down the global aspects of Compass — or Beidou 2 — while underlining near-term efforts to implement a regional capability for the system.

President’s FY09 Budget Proposes $1.2 Billion for GPS Program

President’s FY09 Budget Proposes $1.2 Billion for GPS Program

The White House

President Bush’s Fiscal Year 2009 (FY09) budget released earlier this month proposes an allocation of nearly $1.2 billion dollars for GPS operations, according to the Space and Missile Systems Center’s GPS Wing at Los Angeles Air Force Base, California.

If approved, the budget would support continued development of the GPS III satellite program with a first launch in FY14. The somewhat delayed target date appears to match the prediction of the GPS Wing that the first GPS III launch would be set back a few months as a result of Congressional cuts in the FY08 GPS budget.

GLONASS CDMA Signals Near Approval

GLONASS CDMA Signals Near Approval

Russia appears ready to add code division multiple access (CDMA) signals to its frequency division multiple access (FDMA) GLONASS system.

A final decision is expected next week, according to Sergey Revnivykh, deputy head of the Russian GNSS Mission Control Center, in a February 20 presentation to the Munich Satellite Navigation Conference in Germany. Under the plan, CDMA signals would be introduced at L1 and L5 frequencies near GPS and Galileo signals, beginning with the GLONASS-K generation of satellites that will launch in 2010.

Ivanov GLONASS Flap Obscures Program Reality

Russian Deputy Prime Minister Sergey Ivanov’s criticism of Roscosmos and GLONASS continues to ripple in news columns around the world.
Widely reported in Russian media and picked up and amplified in derivative reports, Ivanov’s complaints focused on GLONASS’s relative inaccuracy, limited coverage, and lack of user equipment.

However, aside from the fact that the person making the remarks was Ivanov — a powerful figure once thought to be in line to succeed Russia’s President Vladimir Putin, none of this is really news. Rather, it seems like another example of the phenomenon that, when people learn of something for the first time, they assume it has just happened.

New GPS Device Tracks Letters in the Mail

The Letter Logger

The new GPS Letter Logger (GLL-1000) by TrackingTheWorld uses a Texas Instruments microprocessor and a u-blox ANTARIS 4 GPS module to help the U.S. Postal Service (USPS) find out where and how long a piece of mail spends in one place.

President’s 2009 Budget Proposal Directs DHS to Implement eLORAN

President’s 2009 Budget Proposal Directs DHS to Implement eLORAN

Antiquated LORAN vacuum tube

The Bush administration appears to have finally made a long-delayed decision to complete implementation of an enhanced LORAN (LOng RAnge Navigation) system to serve, in part, as a back-up to GPS.

Late in the drafting process of the Fiscal Year 2009 (FY09) budget proposal that went to Congress earlier this week (February 4), officials added language “migrating” the LORAN-C system from the U.S. Coast Guard (USCG) to the Department of Homeland Security’s National Protection and Programs Directorate (NPPD). A $34.5-million budget and 294 positions would take part in the migration.

NovAtel to Build Galileo Monitoring Sites

NovAtel Inc. will establish grounds sites in Canada to monitor the GIOVE (Galileo In-Orbit Validation Element) test satellites under a CDN$667,861 (US$671,568) contract recently awarded by the Canadian Space Agency (CSA).

The work includes a parallel cooperative effort to integrate the NovAtel Galileo Test Receiver (GTR), developed for the CSA, into the GIOVE-A Galileo Experimental Sensor Station (GESS), to upgrade the GTR capabilities and to field these GESS stations in Canada.
